Reactive oxygen species favors Varicellovirus bovinealpha 5 (BoAHV-5) replication in neural cells
(Elsevier, 2025-03)Varicellovirus bovinealpha (BoAHV) 1 and 5 are closely related neurotropic alphaherpesviruses with distinct neuropathogenic potential. BoAHV-5 causes meningoencephalitis in calves whereas encephalitis by BoAHV-1 infection ... -
Use of the Micro-Agar Larval Development Test to Differentiate Resistant and Susceptible Cooperia spp. Isolates in Cattle Within the Context of Parasite Population Replacement
(MDPI, 2024-10)Gastrointestinal nematode infections are a global concern in grazing cattle production systems, even more so due to the widespread problem of anthelmintic resistance. In response, early anthelmintic resistance detection ... -
Characterization of Campylobacter fetus adherence, invasiveness, and ultrastructural damage on bovine oviductal cells
(Elsevier, 2025-05)Bovine campylobacteriosis is a distributed worldwide disease caused by Campylobacter fetus. It is a sexual transmitted disease that affects reproductive health in cattle. The objective of this study was to use bovine oviduct ... -
Vestibular syndrome in dairy heifers associated with Mycobacterium bovis: two case reports and strain characterization
(Springer, 2025-03)Bovine tuberculosis is a chronic disease caused by Mycobacterium bovis which rarely causes a neurologic clinical presentation. Tuberculous meningitis is a common clinical finding in young calves in dairy herds where ... -
Transition to Agroecological Practices: Positive Effects on Streams and Biofilms
(Wiley, 2025-02)Transformations in agricultural practices, particularly regarding chemical inputs such as pesticides, affect physical and chemical characteristics and biotic communities of streams. Currently, many conventional production ... -
Pesticide contamination in indoor home dust: A pilot study of non-occupational exposure in Argentina
(Elsevier, 2025-05)Agricultural use of pesticides continues to rise globally. Argentina ranks fifth in use. While pesticides help yields, they also pose risks to human health and the environment. Indoor dust can present high pesticide ... -
Optimization of resource allocation in field phenotyping of sunflower for components of partial resistance to Sclerotinia sclerotiorum on capitula
(Springer, 2025-03-11)In sunflower breeding, plant phenotyping of white rot (WR) resistance requires a significant amount of resources. Thus the present study aimed to evaluate the possibility to make a more efficient phenotyping of WR resistance ... -
Fungal Biota and Mycotoxins Contamination in Soybean Expeller
(MDPI, 2025-03-25)Soybean expeller (SBE), a by-product of soybean oil extraction through the extruding-expelling process, is widely used as a protein source in animal feed and soy-based foods. This study evaluated fungal contamination and ... -
Suspected primary photosensitisation in cattle grazing red clover (Trifolium pratense)
(Taylor and Francis, 2025-04-02)Case history: In April and June of 2024, two outbreaks of photosensitisation occurred in a herd of 354 beef cows and calves in Buenos Aires province, Argentina. Both outbreaks occurred in the same paddock, where red clover ... -
Maize management practices and its relationship with nitrogen indexes and yield
(Spinger, 2025-02-05)Nitrogen fertilization usually increases maize yields, but its impact varies with water availability and plant density. Nitro¬gen indexes like chlorophyll meter readings may help to predict yield variations. Still, their ... -
Post-flowering environment determines zein composition and kernel hardness in maize
(Elsevier, 2025-05)Maize (Zea mays L.) grain endosperm is composed by starch and proteins (mainly zeins, Z1 and Z2) and other minor components. The dry milling industry demands grains with high endosperm hardness, which is determined by both ... -
An evaluation of soil carbon models and their role on finding ways to net-zero carbon in agricultural systems
